ADJUSTABLE msmma jbntmm wm owsf Application filed January 2951929." seen K013353451 ff as to better fulfill the requirements of an in-' vention of this class.

Other features and advantages of the invention will become more readily apparent from the following description and drawings:

In the drawings: Figure 1 is a vertical sectional view through the window structure including sliding sashes and a hingedly mounted storm window provided with the improved fasten-.

ers showing the feasteners in operative position, the storm window being closed. Figure 2 is a View like Figure 1, showing the storm window open.

Figure 3 is a view of the complete fastener removed. 7

Figure 4 is an elevationalview of a special guide fixture.

Figure 5 is an elevational view of the quadrant.

Figure 6 is an edge view of the quadrant. Figure 7 is a transverse sectional view guide and retaining fixture therefor. V Figure 8 is a view of a novel binding'nut. Figure 9 is a perspective view of a storm window attaching bracket.

In Figure 1, the reference character 10 designates generally the window frame, 11 the lower sliding sash, 12, the upper sliding sash, and 13 a vertically swingable storm window mounted upon the frame and disposed in spaced relation to the sashes 11 and 12. 4 s

The improved fastener comprises arcuate slotted quadrants 14, whose offset end15 is pivotally connected to an attaching bracket 16. This attaching bracket is fastened to the frame of the storm .The. I

end of: thequadrant' is directed laterally to provide afinger grip-'17. *f-:;.i i$.-1

. The 'nner. slotted; end portion of the quad;- rant is cooperable with the: slide generally designated bynth "reference, character 18. in

Figure Theslide comprises a';rectangular 'guideiblock 19Thavingfa screw thr ea'deid stein 20 carrying a retaining nut 21: 5 The retains ing nut is threadedfonithe'rstemand isrpr'o vided; with a .pivotally mounted for; hinged finger grip. '22 which may be conveniently at ranged to? facilitate turning ofi the fnut 21'.

c l. The :slideacooperates' with a retaining? fixture .23iof thert-ype seen inFigureI 4, this Joe'- ing rigidly fastene'dlto the window frame at the position: shownl. l. This "fixtureis5 of channel shape iii cross sectioii and is formed with a block. The block 19 is slidable therein; occupying the position seen in Figure 7 with the threaded end extending through and beyond the Y slot. This stem also extends through the slot in the quadrant 14 and that portion extending beyond the quadrant carries the retaining nut 21.

When the device is in place, the storm window may be swung to open position or closed position, without interfering with or striking the sash 11. The guide 19 may be adjusted in the fixture 23, to insure proper clearance, as r the quadrant swings up and out or in and down. 7.

This fastener permits the storm window to be opened a distance permitted by the length of the quadrant and it does not interfere with the opening and closing of the inside sliding sash, whether the storm window is open part way or onl' a small amount for ventilation. This desira le action is produced by the presence of the adjustable guide working in the retaining fixture therefor.

, This fixture being slotted, allows the guide to be moved up and down and the thumbscrew to be tightly fastened to hold the quadrant in any position a to which it has been adjusted.

When the storm window is closed, the thumb screw and guide block onjwhich it is carried should be at the top of the slot in the retaining fixture. When, however, the storm window is opened, the block must be at the bottom of the slot. Otherwise, the quadrant will not clear the inside window sash.

This fastener eliminates rattling and can not be opened from the outside unless the window is openedfar enough to allow the persons hand or arm to pass upwardly between the frame and the storm window. These and other advantages and features have doubtless been made apparent from the foregoing description. Therefore, a more lengthy de- 7 scrgption is regarded as unnecessary".

inor changes in the shape, sizeand rearrangement of details coming within the field of invention claimed may be resorted to, in actual practice, if desired.

I claim: As a new product of manufacture, a storm 'window fastener of the class described comprising a storm window attaching bracket, an elongated arcute slotted quadrant pivotally connected at one end to said bracket, a retaining fixture adapted to be fastened to the window frame, said fixture being of channel shaped cross section and formed with an elongated slot, a guide block slidable in said fixture and including a threaded stem extending through the slot in said fixture and through the slot in said uadrant, and a retaining nut carried by said t readed stem and cooperable with the quadrant to hold the quadrant in different adjusted positions.

In testimony whereof I affix my signature.
